Crash when calling game.CleanUpMap() within ENT:StartTouch

[Spacetech]

The dedicated server crashes when you call game.CleanUpMap() within ENT:StartTouch of a map created brush type entity (a trigger).

The client and server build are 14.0.4.19.

It's not an easy fix because that's not something you're supposed to do in the first place. You are immediately deleting that brush and replacing it with an identical copy before it even has a chance to fully process the collision event, of course things are going to screw up, just use timer.Simple in that case.

The crash kinda makes sense, because if you remove the entity and immediately recreate it, new entity will call ENT:StartTouch again, thus creating an infinite loop.

You could check if the engine is in the process of a physics callback when game.CleanUpMap is called, and queue it if so (same as Facepunch/garrysmod-requests#940 / Facepunch/garrysmod-requests#894).
